Thus we will work this concept into two distinct strategies that have historically had a fair deal of success across different currency pairs. Using such software we can determine the historical profitability and theoretical viability of both of our proposed strategies. When the Risk Reversal hits its bottom 5 th percentile in the past 90 days, buy. If it hits its top 5 th percentile, sell. Close the long position if the Risk Reversal hits its 45 th percentile or above. Cover the short position if the Risk Reversal hits its 55 th percentile or below.
Through the pictured time frame, risk reversal extremes in either direction provided accurate signals for reversal and great timing tools. Yet a major caveat with these results is that the same principles do not work across all currency pairs. One can speculate as to why this may be the case, but it seems relatively clear that we would have needed a different approach to catch major swings in this often-volatile currency pair.
Thus we are left to discuss our second trading strategy: When the Risk Reversal hits its bottom 5 th percentile or below as it relates to previous 90 days, go short. If it hits its top 5 th percentile or above, go long. Close the long position if the Risk Reversal hits its 70 th percentile or below. Cover the short position if the risk reversal hits its 30 th percentile or above. Given that the British Pound performed especially poorly with the Range Trading system, it should be relatively little surprise to see that it is an outperformer with the dissimilar Breakout-style trading strategy.
And though past performance is never a guarantee of future results, such consistent gains suggest that there is more to such gains than pure coincidence. The sudden downturn in performance in the AUDUSD equity curve emphasizes that nothing ever works all of the time, and certainly these strategies were developed with the benefit of hindsight. Yet the relatively intuitive rules behind the strategies should hold some truth.
Attempting to quantify exact trading parameters is consistently difficult, and developing something that works well as a completely automated system is far from a straightforward task. Risk reversals nonetheless show some promise using different trading styles on the major currency pairs, and this suggests that we can use it as another confirming indicator in timing medium-to-longer term swing trades.

Call options provide the holder the right but not the obligation to purchase an underlying asset at a specified price the strike price , for a certain period of time.
If the stock fails to meet the strike price before the expiration date, the option expires and becomes worthless.

Put options give the holder the right to sell an underlying asset at a specified price the strike price. The seller or writer of the put option is obligated to buy the stock at the strike price.
Put options can be exercised at any time before the option expires. Investors buy puts if they think the share price of the underlying stock will fall, or sell one if they think it will rise. Put buyers - those who hold a "long" - put are either speculative buyers looking for leverage or "insurance" buyers who want to protect their long positions in a stock for the period of time covered by the option.

The maximum profit is limited to the put premium received and is achieved when the price of the underlying is at or above the option's strike price at expiration. The maximum loss is unlimited for an uncovered put writer. Options pricing has several components.
At the expiration date of the option, which is sometimes referred to as the maturity date, the strike price is compared to the then-current spot rate. Depending on the type of option and where the spot rate is trading, in relation to the strike, the option is exercised or expires worthless. If the option expires in the money, the currency option is cash settled.
If the option expires out of the money, it expires worthless.
